Answer 1

Answer:

4 is the correct answer

Answer 2

$\huge\sf\pink{Answer}$

☞ Your Answer is 4

━━━━━━━━━━━━━

$\huge\sf\blue{Given}$

✭ cos 0° + sin90°+√3cosec60°

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ The final value?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

So here before solving know that,

◕ cos 0° = 1

◕ sin 90° = 1

◕ cosec 60° = $\sf\dfrac{2}{\sqrt{3}}$

Substituting the values,

➳ $\sf cos0^{\circ} + sin90^{\circ} +√3cosec60{\circ}$

➳ $\sf 1 + 1 + \sqrt{3} \times \dfrac{2}{\sqrt{3}}$

➳ $\sf 1+1+2$ «« √3 gets cancelled »»

➳ $\sf \orange{4}$

$\sf \therefore$ cos 0° + sin90° + √3cosec60° is 4
